A singly linked list has a single pointer in each element, pointing to the next element in the list. Travering the list can only be done in one direction. If you need to find the element prior to a certain element, you must traverse the list from the beginning, looking for an element with a next pointer that points to that certain element.
A doubly linked list has two pointers in each element, pointing to the next and last elements in the list. Traversing the list can be done in two directions.
The advantage of single is only one pointer, saving some space, while the disadvantage is ability to only traverse in one direction.
The advantage of double is ability to traverse in both directions, while the disadvantage is the memory associated with the second pointer and the extra code and time used to update more pointers.
It is easier to insert into a singly linked list.

You copy a singly linked list into a doubly linked list by iterating over the singly linked list and, for each element, calling the doubly linked list insert function.
Advantages of single linked list: # Decrease in storage space per linked list node # Simpler implementation Advantages of double linked list # Decrease in work when accessing a random node # Decrease in work when inserting or deleting a node
A doubly linked list can be traversed in both directions (forward and backward). A singly linked list can only be traversed in one direction. A node on a doubly linked list may be deleted with little trouble, since we have pointers to the previous and next nodes. A node on a singly linked list cannot be removed unless we have the pointer to its predecessor. On the flip side however, a doubly linked list needs more operations while inserting or deleting and it needs more space (to store the extra pointer).
I tried my best to explain all Linked List. For Single Linked List http://www.fansonnote.com/2012/02/single-linked-list/ For Double Linked List http://www.fansonnote.com/2012/02/double-linked-list/ For Multi Linked List http://www.fansonnote.com/2012/02/multi-linked-list/ Hope it will help. Thanks.
Answersingly linked list has the node inserted only at one end. and the pointer corresponds to the next pointer.but in a doubly linked list, the node pointer points to the both previous and the next node.singly linked list has two nodesdoubly linked list has three nodesA doubly linked list makes sense when you need to traverse the list in both directions. You aren't able to do that with a singly linked list.
Yes.

In C programming, a double linked-list refers to a linked data structure that contains a set of links that have been linked sequentially.
typedef struct ListNode {struct ListNode *next;anytype data;} ListNode;typedef struct BiListNode {struct BiListNode *next;struct BiListNode *prev;anytype data;} BiListNode;
